第二颈椎（C2）处于枢转位置，用于颈椎整体的对齐和稳定。由于其椎管在头端较宽，而在尾端较窄，因此从尾端向头端对椎管内侧进行圆顶状切除可导致病变减压，保留C2的背侧部分。作者对33例患者（25例后纵韧带骨化，6例发展性椎管狭窄，2例颈椎病）进行了C2圆顶状椎管扩大成形术，并对其进行了随访观察，随访时间为1 ~ 7年（平均3.5年）。结果在颈椎的减压和稳定性方面令人满意：即使在手术后5年，在扩张的椎管中也没有观察到骨生成再次引起压迫。因此，可以得出结论，这种方法足以取代传统的椎板切除术。
The second cervical vertebra (C2) is in pivotal position for the alignment and stability of the cervical vertebrae as a whole. Since its spinal canal is wider at the cranial and narrower at the caudal end, a dome-like excision of the inner side of the spinal canal from the caudal toward the cranial end results in the decompression of the lesion, preserving the dorsal part of the C2. The authors performed this C2 dome-like expansive laminoplasty on 33 patients (25 cases of the ossification of the posterior longitudinal ligament, six of development spinal canal stenosis, and two of spondylosis) and kept them under follow-up observation, which ranged from 1 to 7 years (mean, 3.5 years). The result was satisfactory in terms of the decompression and stability of the cervical vertebrae: even 5 years after the operation, no osteogenesis was noted in the expanded spinal canal to induce compression again. It thus may be concluded that this method is good enough to replace conventional laminectomy.
